Bayern Munich chairman Karl-Heinz Rummenigge has threatened to take legal action against FIFPro as Manchester United and Chelsea target Franck Ribery's plot to quit the German giants took another twist.

The game's global union for professional players revealed they intend to support the want-away France international's bid to engineer an exit from the Allianz Arena this summer, with a host of elite European suitors vying for the winger's services.

Real Madrid lead the chase for the £60million-rated 26-year-old and
Bayern are braced for Ribery to exploit a FIFA loophole as they
desperately seek to hold onto him.

Get out clause: Ribery could invoke the Webster rule to quit Bayern this season

'Everything has a limit and with the stance FIFPro has taken, they have gone
overboard,' Rummenigge told Munich-based German daily TZ.

'By releasing an official notice, FIFPro are inviting players to break their
contracts, and this is simply madness.

'What football needs now is stability and not players breaking their
commitments. We will examine our legal possibilities and we will ask, if the
time comes, for indemnification. FIFPro have exceeded their limits.'

In light of FIFPro's support, it is understood that Ribery is contemplating Article 17 of FIFA regulations - commonly known as the Webster rule - which states that any player aged between 23 and 28 is permitted to walk away from his club, provided that he has served a minimum of three years of a four or five-year contract.

Ribery is free invoke the clause this season, enters his third year of a five-year deal at Bayern.

But Rummenigge is assured the
player does not want to leave amid fears the club would stand to lose over £40million on the player, who could depart for as little as £14million in compensation fees.

'We are calm, since we know that Ribery will remain with
us. He is not forcing a departure,' he added.

'We are against this [FIFPro] opinion, which is something that does not
correspond to Ribery’s character'

Rummenigge was also quick to dismiss the notion that the star was feigning an injury as part of his plan to hatch an escape, insisting the former Marseille man is behaving perfectly normal despite constant speculation surrounding his future.

He said: 'I must make one thing very clear. Franck is currently injured. He is not
faking the injury nor is he a problematic player.

'He is behaving in the correct manner. The fact
that he is worried about the offer from Real Madrid is perfectly normal.'
